Specifications
CONTACT RATING: B contact material: 0.4 VA max. @
20 V AC or DC max. See page F-35 for additional ratings.
ELECTRICAL LIFE: ETX1 models: 60,000 make-and-break cycles at
full load. All other models: 30,000 cycles.
CONTACT RESISTANCE: Below 20 m Ω typ. initial @ 2-4
V DC, 100 mA, for both silver and gold plated contacts.
INSULATION RESISTANCE: 109 Ω min.
ELECTROSTATIC DISCHARGE (ESD) RESISTANT OPTION:
M3 & S3 insulating actuator only: 9,000 V DC min. @ sea level,
actuator to terminals. F1 conductive bushing only: Dissipates
up to 20,000 V DC from actuator to ground. M3 & S3 actuator
and F1 bushing options are not recommended for use together.
DIELECTRIC STRENGTH: 1000 Vrms min. @ sea level.
OPERATING TEMPERATURE: –30ºC to 85ºC.
SOLDERABILITY: Per MIL-STD-202F method 208D, or
EIA RS-186E method 9 (1 hour steam aging).
DEGREE OF PROTECTION: IP57; Protection against harmful dust
deposit, full-scale voltage protection, temporary immersion.
PACKAGING: Surface mount switches are shipped in tape and reel
packaging, see page F-31 for drawings and reel information.
Materials
CASE & BUSHING: Glass filled nylon 6/6, flame retardant, heat
stabilized (UL 94V-0) or glass filled 4/6 nylon, flame retardant, heat
stabilized (UL 94V-0). F1 conductive bushing option is impregnated
with carbon fibers.
ACTUATOR: M3 & S3 anti-static actuator: Nylon 4/6, black standard
(UL 94V-0). All other actuators: Brass, chrome plated. Internal
o-ring seal standard with all actuators.
SWITCH SUPPORT: Brass, tin plated.
CONTACTS & TERMINALS: B contact material: Copper alloy,
with gold plate over nickel plate. Q contact material: Copper
alloy, silver plated. See F-35 for additional contact materials.
TERMINAL SEAL: Epoxy.
NOTE: Any models supplied with Q, B, G, P or R contact material are RoHS compliant
and compatible.
NOTE: Specifications and materials listed above are for switches with standard options.
